Industrial Hemp Is North Carolina’s Newest Crop!

There’s a lot of excitement about a new crop for North Carolina that is just now being harvested: industrial hemp!

Industrial hemp has been grown around the world for hundreds of years. Hemp is a valuable agricultural commodity in over 30 countries where its stalk, seed, and flowers are processed into multiple products including food, beverages, fiber, textiles, paper, construction and insulation materials, cosmetic products, and animal feed.

Industrial hemp is the same species as marijuana (Cannabis sativa) but the two crops are distinguishable by their tetrahydrocannabinol (THC) content. THC is a cannabinoid produced by the plant that causes the high from marijuana. Hemp must have less than 0.3% THC. Plants that have more than 0.3% THC content are classified as marijuana.

Cannabis plants produce many other cannabinoids besides THC. Cannabidiol, or CBD, is a cannabinoid that has attracted a lot of attention for its pharmaceutical effects and is used to treat epilepsy, depression, pain, and other ailments. Many hemp growers are interested in the high-value CBD production.

Demand for hemp products is high in the U.S. but until recently hemp production has been very limited due to federal drug enforcement laws. According to the National Conference of State Legislatures, 38 states and Puerto Rico considered legislation related to industrial hemp in 2017. Some bills clarified existing laws and some established new licensing requirements and programs; 31 states now allow industrial hemp production for commercial, research, or pilot programs.

Industrial hemp production was legalized in North Carolina in 2016 as part of the Pilot Research Program. A North Carolina Industrial Hemp Commission was formed and North Carolina State University, North Carolina A&T State University, and the North Carolina Department of Agriculture & Consumer Services are all participants in the pilot program.

Dr. Tom Melton is the Deputy Director of NC State Extension and also the Chair of the NC Industrial Hemp Commission. “The NC Industrial Hemp Commission is pleased to see over 100 growers participating in the first year of the Pilot Research Program and to see so much excitement among them,” Melton said. “Equally exciting is the number of entrepreneurs participating in the research project by helping to pilot new processing and marketing opportunities for growers so we can learn better how the whole system may work and increase economic development opportunities in rural North Carolina.”

All growers in the pilot program are required to conduct research to further the understanding of hemp production, harvesting, processing, and marketing in North Carolina. Research areas include variety selection, seed production, fertility, insect and disease management, weed management, greenhouse production, market feasibility, value-added production, oilseed production, energy production, and more.

The first hemp crop was planted in North Carolina in late spring and some fields are already being harvested. Dr. Jeanine Davis is a NCSU Horticulture Specialist who is conducting industrial hemp research in western North Carolina. Davis has already harvested some of her research plots with a combine and will soon be doing taste tests of the edible seed. “There is a lot of misinformation out there about hemp,” Davis said. “Many people have gotten the impression that it will just grow itself with minimal inputs or care. But if you want to make money off of this crop then you have to treat it as you would any valuable cash crop, and not plant it in your worst field and hope it makes it. Since this is such a new crop in North Carolina we are still trying to figure out exactly what it needs to succeed.”

Industrial hemp can be grown as an agronomic crop or more intensively as a horticultural crop, depending on what it is being grown for (fiber, seed, CBD oil, etc.). Some growers in North Carolina are growing industrial hemp in greenhouses and high tunnels for medicinal CBD oil production. Guilford County Agriculture Agent John Ivey is well positioned to help these growers because he has experience working with a legal cannabis crop. “I’m excited that our farmers have chosen to be early adopters and taken ownership of the research that hopefully will improve their farms’ production and sustainability,” Ivey said.

Since I have no experience with hemp (like most agents in the state!), I asked Ivey if I could tag along with him to visit one of his growers to learn about high tunnel hemp production. We visited DSW Farms in Greensboro where grower Sager West is growing hemp in pots in a high tunnel using organic practices.

This first year of production has been challenging because the transplants were already flowering when he received them. Consequently, yields are expected to be lower than normal this first year.

West is growing hemp for CBD production. CBD is primarily found in sticky, crystal-like hairs called trichomes on the buds and surrounding leaves and bracts of female flowers. He will harvest and cure the flowers then send them to a processor to have the CBD oil extracted from the trichomes.

High tunnel hemp pests include spider mites, aphids, and caterpillars. Beneficial insects can help with pest control. This photo shows a tiny parasitic Ichneumonidwasp pupa the size of a grain of rice next to a dead caterpillar that was eaten by the wasp larva. Photo by Debbie Roos.

West said that this first year of production has been a big learning curve for everyone. Growers got a late start in planting due to the application process so it was not a typical production year. He is already looking forward to applying what he learned to next year when he plans on growing hemp both in the tunnel and the field.

“I’ve been passionate about hemp and its potential to help farmers for over ten years and so the legalization of hemp production in North Carolina has been a blessing and a dream come true for me,” West said. “I’m eagerly looking forward to helping to shape a new sustainable industry for North Carolina.

Because all North Carolina hemp growers are on a steep learning curve this year, opportunities to network and learn from other growers and researchers are highly prized. About 80 growers, extension agents, and researchers attended an Industrial Hemp Field Day conducted by NC Cooperative Extension at the Piedmont Research Station in Salisbury on August 16. The field day was an opportunity to network and get an update on the research being conducted at the station.

Several varieties were planted at the research station in mid-June. This is about a month later than the ideal planting season but since this is the first year the crop has been planted in the state everything is a little behind.

The bumble bees were all over the male hemp flowers. Honey bees will also visit hemp which is primarily wind pollinated. Beekeepers in other parts of the country where hemp is grown have found a good market for hemp honey.

Our researchers are busy learning about hemp pests, diseases, and weeds. Pests include caterpillars (corn earworm pictured below), Japanese beetles, grasshoppers, leafminers, spider mites, aphids, and more. There are currently no pesticides labeled for use on hemp in the U.S. Researchers are trying to determine which products work on hemp so they can apply for specialty labels. There is also interest in organic hemp production.

The field day provided many opportunities for networking among participants. I learned a lot talking with others and made plans to visit some growers in other counties. We are all trying to learn from each other!

About Growing Small Farms

From Bear Creek to Bynum, Silk Hope to Moncure, the Chatham County landscape is dotted with small farms. Farmers throughout the county are known for growing a great diversity of agricultural products, including vegetables, fruits, cut flowers, herbs, poultry, beef, pork, dairy products, and other goods. As one of the few counties in the state to actually experience an increase in the number of farms in the past decade, Chatham is also “growing small farms.”

Many of Chatham’s newer farms are owned by first-generation farmers attracted to the challenges and rewards of making a living from the land. Chatham has a large concentration of farms practicing organic and sustainable agriculture that strive to be environmentally responsible, economically viable, and socially just. In a time when the trend in conventional agriculture is towards fewer and larger farms and many of North Carolina’s “conventional” farmers are struggling, the sustainable and diverse agriculture practiced by Chatham’s small farms provides the best hope for keeping agriculture a viable part of the community.

Chatham’s proximity to upscale Triangle-area markets ensures a steady demand for the organic and sustainably-grown crops produced by area farmers. Four farmers’ markets in the county provide residents with ample opportunities to shop and interact with local growers throughout the long growing season. Many area farms offer opportunities for on-farm visits where visitors get the chance to make the connection between food and agriculture.

Small farms also provide many indirect benefits. They help maintain open space valued by people and wildlife. Visitors flock to Chatham for the beauty of its rural landscape. The challenge is to preserve this rural landscape in the face of development pressures from Raleigh and Chapel Hill. One way to preserve the rural landscape is to help keep farms in the county.

The Chatham County Center of North Carolina Cooperative Extension has long recognized the value and importance of the sustainable agriculture practiced by small farms in the area. In 1994, the Chatham County Center created a new county agent position to support the unique needs of these small farmers. Today, this position is fully funded by the Chatham County government, which recognizes the value of sustainable agriculture to the county. Chatham County Agricultural Extension Agent Debbie Roos works with farmers to promote increased awareness, understanding, and practice of sustainable agriculture through monthly educational workshops, a website, on-farm visits, and other consultation.

Roos developed the Growing Small Farms website in 2002 after a survey revealed that approximately 95% of local farmers regularly used the Internet. The site has since grown to over 500 pages and receives over 25,000 visitors each month. Growing Small Farms is also on Twitter and Facebook.

Farms don’t exist without consumers, so please take the time to get to know the farmers in your community and support their efforts to keep Chatham County green! Visit our farmers’ markets to purchase the freshest vegetables, fruits, meats, baked goods, and other products, all grown or made locally by the person selling it to you. The Buy Local Guide lists community supported agriculture farms, on-farm stands, pick-your-own farms, wineries, and more. Check out the local farm profiles and farm photos on this website for a glimpse of the diversity that allows Chatham’s farms to prosper.
